Light Source Efficiency: Exploring Irradiance

Grades:
6-8
Lesson Number:
4
Description:

This lesson explores the concept of irradiance by having students use a Vernier Pryanometer. Using the “Light Source Efficiency” worksheet to guide their work, students measure irradiance as compared to the Sun’s irradiance to see what would be the best...

Sunlight Incident Angle

How to Measure Output of Solar Modules

Grades:
4-6
Unit:
Lesson Number:
5
Description:

Students will measure output from solar module before a load is attached and relate it to real world output. They will make these measurements using a multimeter and be able to determine the optimal angle at which their module generates a current flow....

Learning Goal(s):
Students will demonstrate that solar modules create electricity when light strikes the module. Students will determine the optimum angle for the generation of current by a solar cell when given a light source (indoors or outdoors using the sun). Students will be able to effectively use a digital multimeter to measure current and voltage produced by a solar cell.
